During class, students seem to understand the concepts. However, they don’t do well on the tests. I offer extra help before and after school and at lunch, but few students take advantage of it. I’m a first-year biology teacher, so I’d appreciate some suggestions on how to encourage students to ask questions or seek help when they need it.

It sounds like your question has several components. First of all, how do you know your students understand the lesson concepts? Teachers often say “Any questions? Good.” When there are no questions, the teacher assumes that everyone understands. Try to provide a context or focus, such as “Any questions about the difference between eukaryotic and prokaryotic cells?” And then wait a few seconds for students to think about their learning and formulate their questions. Frequent formative assessments—bellringers, “ticket out the door,” brief quizzes, responses via clickers or white boards, thumbs up—may also help students to reflect on what they know or don’t know and give you some concrete feedback on their understanding during each lesson.
When can your students get extra help? It’s hard for students who ride busses to come in early or stay late. Many students are involved in extracurricular activities or have afterschool responsibilities. And it’s hard to blame students for not wanting to give up lunch, often the only chance they have to socialize or relax. Some teachers have virtual “office hours” in the evenings or on weekends to provide assistance via e-mail or a discussion forum. But as today’s students seem to prefer social media to e-mail, you could take advantage of this interest. For example, even though Edmodo looks like Facebook, it’s a microblogging site that a teacher can set up for students to collaborate, ask questions, and share resources. Teachers can also post their own resources such as quizzes or study guides. It’s accessible 24-7 via computers or smartphone apps. The teacher can moderate the site and delete inappropriate posts.

The class period may be the only time you can interact with students. Is your classroom a “safe” place for them to ask questions? Do students know how to ask for assistance? Is asking considered a sign of weakness? Are students embarrassed to ask questions? No matter how trivial the question or comment, never belittle it, reply with sarcasm, or allow other students to laugh at it.
After you’ve gone over directions for an activity, it’s frustrating when students raise their hands and ask, “What are we supposed to do?” If you say “I already told you. Figure it out,” students may assume that other kinds of questions will get the same response. Model how to refer to the printed directions or how to ask a partner.
It may also be helpful to model the type of questions students could ask related to understanding: “Could you please explain that again?” “I don’t understand… Does this mean that” “But what about…” “What would happen if… ”
If you notice more than one or two students have the same question during an activity, offer some “group therapy:” meet with a small group of students to go over the concept or procedures. If you find all of the groups are struggling with a concept or procedure, have a brief mini-meeting to review.
Teachers need to walk a fine line between being helpful and taking over a student’s thinking. Some students become dependent on teachers, constantly asking questions for verification (“Is this correct?” “Am I doing this right?”) Show them how to refer to the rubric or to the directions to help them develop initiative and independence.
As a student, I enjoyed figuring out something for myself. I became annoyed with teachers who hovered over my shoulder, asking if I needed help. You’ll have to determine when students really need help and when they need time to think through a problem themselves. I had a student who constantly asked questions in a soft voice. I thought at first he needed my help, but it turned out that he was thinking out loud. We made a deal—if he did indeed require some help, he would raise his hand. Otherwise, I left him alone with his thoughts.
In the classroom, teachers are usually the ones asking the questions. I’m glad you’re trying to foster students as questioners.
